“…While advanced decomposition algorithms (called SSDP in [35]) have solved efficiently the deterministic counterpart of 1|| j T j , the robust counterpart cannot benefit from these techniques because the binary variables would depend on each vector p ∈ U . Specifically, the resulting formulation would have a pseudo-polynomial number of variables for each p ∈ U , making SSDP completely unrealistic [14]. Finally, notice that we also disregard the disjunctive constraints formulation (see [5]).…”

We investigate algorithms that solve exactly the robust single machine scheduling problem that minimizes the total tardiness. We model the processing times as uncertain and let them take any value in a budgeted uncertainty set. Therefore, the objective seeks to minimize the worst-case tardiness over all possible values. We compare, through computational experiments, two types of solution algorithms. The first combines classical MILP formulations with row-andcolumn generation algorithms. The second generalizes the classical branch-andbound algorithms to the robust context, extending state-of-the-art concepts used for the deterministic version of the problem. By generalizing the classical branch-and-bound algorithm we are able to assemble and discuss good algorithmic decisions steps that once put together make our robust branch-andbound case attractive. For example, we extend and adapt dominance rules to our uncertain problem, making them an important component of our robust algorithms. We assess our algorithms on instances inspired by the scientific literature and identify under what conditions an algorithm has better performance than others. We introduce a new classifying parameter to group our instances, also extending existing methods for the deterministic problem case.

“…Indeed, ample anecdotal evidence suggests that managers often make costly attempts to rationalize their actions and influence the opinions or beliefs of shareholders, analysts, and investors through voluntary disclosures-via the media, letters to shareholders, advertisements, telemarketers' phone calls, or costly road shows. In particular, managers often justify actions relating to expansions, scale backs, changes in payout policy, and their firms' competitive strategies (e.g., Soter, Brigham, and Evanson [1996], Bergstein [2002], DeTienne and Hoopes [2004], Lang and Lundholm [2000]). 1 Such resource allocation implications of voluntary disclosure have received little attention in the literature, which, for the most part, has focused on the valuation implications of disclosure.…”

We examine the valuation and capital allocation roles of voluntary disclosure when managers have private information regarding the firm's investment opportunities, but an efficient market for corporate control influences their investment decisions. For managers with long-term stakes in the firm, the equilibrium disclosure region is two-tailed: only extreme good news and extreme bad news is disclosed in equilibrium. Moreover, the market's stock price and investment responses to bad news disclosures are stronger than the responses to good news disclosures, which is consistent with the empirical evidence. We also find that myopic managers are more likely to withhold bad news in good economic times when markets can independently assess expected investment returns. * University of Houston; † Texas A&M University.
